Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The package has no lifecycle scripts, and the cited agent-directory behavior is consistent with skill setup. The inspected source does not establish an active attack or an unresolved dangerous capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-10T15:37:55.424Z - **Finished:** 2026-10-10T15:38:23.725Z - **Download time:** 1295 ms - **Static scan time:** 1504 ms - **AI review time:** 25501 ms - **Total time:** 28301 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed attack surface was identified. The inspected skill setup code writes skill files under platform-specific agent directories. - **Trigger:** A skill installation operation invokes the installation helper. - **Impact:** Skill files may be added to an agent directory as part of setup; no malicious impact is established by the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T15:38:23.725Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper creates the resolved skill directory and writes downloaded skill files; the inspected excerpts do not show an npm install hook or an unconsented broad configuration change. - **Rationale:** The package has no lifecycle scripts, and the cited agent-directory behavior is consistent with skill setup. The inspected source does not establish an active attack or an unresolved dangerous capability. - **Files touched:** dist/mcp.cjs ### Review decision - **Verdict:** Clean - **Confidence:** 78.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines the package entrypoints and dependencies but no install lifecycle hooks., dist/mcp.cjs maps skill destinations to platform-specific home directories and exposes a skill installation helper that creates directories and writes files., Skill files are downloaded from a supplied server base URL with an Authorization header; this supports agent skill setup, but the inspected code does not establish an unrestricted credential-forwarding attack. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.499. - Review the evidence and your use of @whalent/agent-core@0.3.499 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
